Control of the progress of underground works
Best services
MAXIMUM PRECISION AND ACCURACY OF THE PROFILE
Tunnel surveying is crucial to the success and profitability of subway excavations. From initial excavation to staking out and acceptance of works, our services cover all stages.
To ensure high quality standards, we carry out control measurements and generate backups once the construction work is completed. During excavation, we carry out continuous measurements and evaluations to provide accurate position and direction information, ensuring efficient and safe construction at the tunnel face.

CONVENTIONAL TUNNELS
Our classic motor laser system delivers precise axis-related laser point marking directly on the tunnel feed face. Using our advanced EUPALINOS software, we process, evaluate, and document all geodetic tunneling measurements, providing detailed staking lists and control sketches for the laser system.
This powerful combination of laser technology and geodetic software ensures highly accurate tunnel excavation, enabling precise alignment, efficient workflows, and reliable results in every tunneling project.
TUNNELS WITH GUIDANCE SYSTEMS
We use our proven TAUROS guidance systems to accurately and continuously record the spatial position and orientation of tunnel boring machines (TBMs). This advanced technology compares the current position and alignment with the tunnel axis, ensuring real-time monitoring and control. The data is permanently displayed to the machine operator, guaranteeing precise tunnel excavation, higher efficiency, and maximum safety throughout the construction process.
